McLaren CEO Zak Brown has taken another swipe at Red Bull F1 team boss Christian Horner for “making excuse🌟s” and “not taking owneౠrship” over a number of issues.

Since McLaren’s re𝔉surgence on-track, Brown hasn’t been afraid to lock horns with Horner.

Brown was vocal in his criticism of Red Bull when they ဣexceeded F1’s cost cap.

𝐆He claimed Red Bull’s overspending ‘constituted cheating’ which didn’t go down w🧸ell.

More recently, B♌rown was outspoken amid Horner’s inappr🥃opriate behaviour scandal calling for “transparency”.

Simil🀅arly, the Americꦏan poked fun at Red Bull when they lost Adrian Newey, stating the team will likely lose more key personnel with “CVs floating around”.

In an interview with the , Brown shed light on his relationsh꧅ip with Horner and why it has deteriorated.

"I've known Christian for ꧒about 25, 30 years. We used to race against each other. I would say we used to get on,” he said.

"I believe in transparency. I believe in putting your hand up when you get something wrong. The cost cap, the excuses behind tha♏t, I never really heard a 'we just got it wrong'. I heard excuses and not taking ꦅownership.

"When someone breaches the cost cap, and doesn't seem to kind of take it seriously, that's kind of hitting the integrity and coreꩵ of the sport.

"To me, it's not🧜 personal. It's protectꦉing our sport.”

Brown again made reference to Horner’s pre-season ♏controversy, adding it wasn’t “consistent with our values”.

"And when I see things not consistent with our values, I'm going to speak up abou🍷t it because it's important people understand where we're coming from,” he added.

"I realise that's not ne🐻cessarily always going to be popular, or make friends with everyone in the pit lane, but as long as⛦ I'm friends with McLaren, our fans, our partners, that's what's most important to me."
